Garmin Approach S42 GPS Watch

Overview

The Garmin Approach S42, released in August 2021, represents the sweet spot in Garmin's GPS golf watch lineup — positioned below the premium S62 and S70 models, but delivering the core features that most golfers actually use on the course. At its current market price of around $149, it offers one of the best feature-per-dollar ratios of any dedicated GPS golf watch available.

The S42's headline capability is its database of 41,000+ preloaded golf courses — among the largest of any GPS golf watch — with free lifetime updates delivered wirelessly via Bluetooth. This means golfers can access detailed layouts for virtually any course they're likely to play, anywhere in the world, without subscription fees or per-course purchases.

What separates the S42 from cheaper GPS options isn't just course coverage — it's the intelligence of how it presents that data. Auto Shot Detection automatically logs every shot taken during a round, eliminating the manual yardage entry that older GPS watches required. PinPointer provides a digital compass pointing directly at the pin from anywhere on the course, including from behind trees or in ravines where the green isn't visible. Green View lets golfers see an overhead representation of the hole layout and manually adjust the pin position to match the day's setup.

All of this data feeds seamlessly into the Garmin Golf app, which builds a comprehensive statistical picture of each golfer's game over time — tracking average distances per club, scoring averages by hole position, proximity to the pin, and handicap.

Score Breakdown

Our aggregate analysis gives the Garmin Approach S42 an overall score of 8.3/10:

What People Love

The Garmin Golf app ecosystem. What truly differentiates the S42 from generic GPS watches is the depth of the Garmin Golf app. Every round's shot data syncs automatically, building a database of your game that gets more valuable over time. After months of use, golfers can see precisely which clubs they hit inconsistently, where they consistently lose strokes, and how their handicap is trending. A GolfWRX user who conducted a head-to-head test against competing watches noted that "Garmin Golf vs Shot Scope's platform" was the deciding factor in recommending the S42, with the Garmin ecosystem offering better long-term value.

PinPointer — the underrated hero feature. Every course has blind shots. The S42's PinPointer provides a compass arrow pointing toward the pin from any location on the course. Multiple reviewers described this as a "must-have" feature they hadn't anticipated needing until they encountered a blind par-3 or a dogleg where the flagstick wasn't visible. The feature works independently of the GPS layout data, using directional accuracy to point to the target.

41,000+ courses with free lifetime updates. The S42's course database is free to update forever. No subscription. No per-course fees. Competitors at this price point sometimes limit free updates or charge for additional courses. The combination of breadth (41,000+ courses in over 100 countries) and update policy is a genuine differentiator.

Sunlight-readable touchscreen. The S42's 1.2-inch full-color touchscreen is consistently praised for readability in direct sunlight — a critical capability for a golf watch. Competitors at similar price points sometimes use lower-quality screens that wash out in bright conditions.

Automatic shot detection and effortless stats. Auto Shot Detection captures full swing shots without manual input, feeding distance data into the Garmin Golf app automatically. Golfers who previously used rangefinders or manual GPS trackers report that the elimination of manual input changes how they interact with the device on the course.

What People Hate

No slope-adjusted distances. This is the S42's most commonly cited limitation. Garmin's own S62 and S70 models include slope adjustment (PlaysLike distances corrected for elevation change), which the S42 omits. For golfers who play hilly courses where elevation dramatically affects club selection, the absence of slope is a meaningful gap. The Bushnell Ion Elite and Shot Scope V5 at similar price points offer slope capability.

15-hour GPS battery for back-to-back play. For standard 18-hole rounds, 15 hours is comfortably sufficient. But for golfers who play 36-hole tournament days, the S42 may not survive without recharging between rounds. One Amazon reviewer specifically called out this limitation after the watch died on the back 9 of their second round.

Auto Shot Detection misses short-game shots. The accelerometer-based Auto Shot Detection reliably captures full swing shots but struggles with chip shots, bump-and-run approaches, and putts. Golfers who want comprehensive tracking of their short game will find the detection incomplete. The Shot Scope V5, which uses a more sophisticated sensor array, offers more comprehensive shot tracking.

Competitors

Garmin Approach S70 ($499.99): The top of Garmin's golf watch lineup. Adds slope-adjusted distances, a larger AMOLED display, Virtual Caddie club recommendations, full smartwatch features (offline maps, streaming music), and more robust fitness tracking. Worth the premium for serious golfers who want an all-in-one device.

Bushnell Ion Edge GPS Watch ($149.99): The S42's closest competitor on price. The Ion Edge features a touchscreen, 38,000+ courses, and slope-adjusted distances — a significant advantage over the S42. Where the S42 wins is on course database size (41,000 vs 38,000) and the superior Garmin Golf app ecosystem.

Shot Scope V5 GPS Watch ($299): More expensive, but offers the most sophisticated automatic shot tracking of any GPS watch. The V5 uses small sensors placed in club grips to track every shot with high precision, including short-game shots the S42 misses. For data-obsessed golfers who want complete round analytics, the Shot Scope justifies its premium.

Who Should Buy This

The Garmin Approach S42 is the ideal GPS golf watch for: recreational golfers making their first GPS watch purchase; golfers who play at 2-3 different courses per year and want reliable yardage plus app integration; senior golfers who prioritize simplicity and readability; and any golfer who plays standard 18-hole rounds and doesn't need slope.

Who Should Skip

If slope adjustment is important to you, skip the S42 and consider the Bushnell Ion Edge or Garmin S70. If you play 36-hole days or need an all-day device, consider the S70 which has significantly better battery life. If you want the absolute best automatic shot tracking, the Shot Scope V5 is in a different league for short-game data.

The Bottom Line

The Garmin Approach S42 delivers the most important GPS golf watch features — comprehensive course coverage, Auto Shot Detection, PinPointer, and best-in-class app integration — at a price that makes it accessible to a wide range of golfers. Its limitations (no slope, limited short-game tracking) are real but predictable at this price point. For golfers who want a reliable, well-rounded GPS golf watch without breaking the bank, it's an outstanding choice.
